HTML#

The HTML node provides operations to help you work with HTML in n8n.

HTML Extract node

The HTML node replaces the HTML Extract node from version 0.213.0 on. If you're using an older version of n8n, you can still view the HTML Extract node documentation.

Cross-site scripting

When using the HTML node to generate an HTML template you can introduce XSS (cross-site scripting). This is a security risk. Be careful with un-trusted inputs.

Operations#

Generate HTML template: Use this operation to create an HTML template. This allows you to take data from your workflow and output it as HTML.
Extract HTML content: Extract contents from an HTML-formatted source. The source can be in JSON or a binary file (.html).
Convert to HTML Table: Convert content to an HTML table.

The node parameters and options depend on the operation you select. Refer to the sections below for more details on configuring each operation.
